ID-based authenticated multiple-key agreement protocol from pairings

To achieve secure data communications, participants should be authenticated and a new session key must be agreed securely. An authenticated key agreement protocol combining the meaning of user authentication and key agreement is necessary for these purposes. This paper proposes a new ID-based multiple-key agreement protocol. The authenticity of the protocol is provided by a signature scheme. The proposed protocol allows two parties to establish n(2) common secret keys if they compute and send n Diffie-Helman's public keys. The security attributes of the proposed protocol are examined using heuristic methods.
